Embodiment Construction

[0024] In order to make the above objects, features and advantages of the present invention more comprehensible, the present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments. Apparently, the described embodiments are some, but not all, embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.

[0025] There are two positioning technologies for head-mounted display devices, one is Outside-in Tracking technology, which is currently the mainstream, but this technology also has some disadvantages, such as the user's movable range is limited to the sensor monitoring range , requires the use of external sensors, is easily affected by obstructions, etc. The other is the inside-out tracking technology (Inside-out Tracking)....

Abstract

The invention discloses head-mounted display equipment, and a handle and a location tracking method thereof. The method comprises the following steps: controlling an electromagnetic wave emitter in the head-mounted display equipment to generate and emit electromagnetic waves; receiving corresponding induced electromotive force induced by an electromagnetic wave receiver in the handle and determining relative position and direction information sent after relative position and direction information of the electromagnetic wave receiver and the electromagnetic wave emitter are determined accordingto the induced electromotive force; and determining the position of the handle in the space according to the received relative position and direction information. According to the embodiment of the invention, an electromagnetic positioning technology is adopted, so that the influence of a shielding object is avoided, the positioning precision is ensured, and a user can freely move conveniently during operation.

Description

technical field [0001] The present invention relates to the technical field of head-mounted display devices, in particular to a head-mounted display device, a handle and a location tracking method thereof. Background technique [0002] With the gradual maturity of head-mounted display device technology, various technologies surrounding virtual display devices have also developed rapidly, including virtual reality (Virtual Reality, VR), augmented reality (Augmented Reality, referred to as AR), mixed reality (Mix Reality, referred to as MR), among them, VR is to let users fully immerse in the virtual world, AR is to add virtual information to the real environment to enhance the real environment, and MR is to mix the real world and the virtual world. Together, to generate a new visual environment, the new visual environment contains both physical entities and virtual information. [0003] In order to realize the above VR, AR or MR functions, head-mounted display devices need t...
